Auckland Transport has changed more than 20 terms and conditions for its public transport Hop card after a Commerce Commission review found some were "potentially unfair".
The commission tested the Hop card's compliance with the Fair Trading Act after public complaints.
"Our review identified a number of issues in the terms of use which we considered to be potentially unfair to consumers," commissioner Anna Rawlings said this morning.
"Examples included terms limiting the validity period of unused cards, allowing variation of the terms of use for the card without notice, limiting the right to obtain a refund or transfer of unused credit for non-registered cards, and explanations of the consequences of not tagging off," Rawlings said.
Auckland Transport has changed more than 20 of its terms and conditions - extending the validity period of unused AT Hop cards from two to six years and limiting the blocking of cards in cases where passengers repeatedly fail to tag off.
